[Java] Optimize statistics collector
* Optimize statistics collector by collecting statistics of multiple DBs in a single thread rather than starting up a new thread for each DB.
* Also, fix packaging of jnilib file on OS_X platform.
* Diff review: https://reviews.facebook.net/D20265
[Java] Add documentation on interdependency of dispose call of RocksObjects
* Remove transferCppRawPointersOwnershipFrom function.
- This function was setting opt.filter_ and thus filter_ to be null. This way there is no
one holding reference for filter object and can thus be GC'd which is not the intention.
Replaced it with storeOptionsInstace which stores options instance. Options class
internally holds Filter instance. Thus when Options is GC'd, filter reference
will be GC'd automatically.
* Added documentation explaining interdependency of Filter, Options and DB.
* Diff review: https://reviews.facebook.net/D20379

* Add JAVA_LDFLAGS, which does not include gflags
* rocksdbjava library now uses JAVA_LDFLAGS instead of LDFLAGS
* java/Makefile now includes build_config.mk
* rearrange make rocksdbjava workflow to ensure the library file is correctly
included in the jar file.

Improve documentation for RocksEnv and its C++ resource. Specifically,
the result of RocksEnv::Default() is a singleton, and the ownership
of its c++ resource belongs to rocksdb c++. As a result, calling
dispose() of the return value of RocksDB::Default() will be no-op.

Summary:
1. Move disOwnNativeHandle() function from RocksDB to RocksObject
to allow other RocksObject to use disOwnNativeHandle() when its
ownership of native handle has been transferred.
2. RocksObject now has an abstract implementation of dispose(),
which does the following two things. First, it checks whether
both isOwningNativeHandle() and isInitialized() return true.
If so, it will call the protected abstract function dispose0(),
which all the subclasses of RocksObject should implement. Second,
it sets nativeHandle_ = 0. This redesign ensure all subclasses
of RocksObject have the same dispose behavior.
3. All subclasses of RocksObject now should implement dispose0()
instead of dispose(), and dispose0() will be called only when
isInitialized() returns true.
